Abstract
An apparatus and a method for guiding and cutting a continuously advancing yarn during a package doff in a takeup device. In this connection, a movable yarn guide guides the yarn substantially parallel to a package or a winding tube, which is driven by a drive roll. The yarn guide is followed by a suction device, which consists of a pneumatic suction inlet end and a cutting device. The suction device cooperates with a transfer device for purposes of cutting the yarn during the package doff and receiving the loose end of the advancing yarn. To protect the yarn during the package doff, the yarn guide extends in the yarn path upstream of the driven tube, and the suction device downstream thereof. For catching the yarn and winding initial layers thereof on a new winding tube that is driven by the drive roll, the yarn is guided in a yarn guide groove provided on the circumference of the drive roll or on the circumference of the new winding tube so that the yarn is protected within the contact zone between the accelerating winding tube and the drive roll.
